LMS is fairly easy to do.
Use something like this
[@Main]
#SAY
Hello there <$USERNAME> I am the LastManStanding master.\
I am here to organise an event every Sunday at 6pm to 7pm GMT.\\
What would you like to do?\\
<Take part in the event/@tp> <Explination about the event/@exp>

#SAY
LastManStanding is an event which everyone can take part in.\
The room will open 5 minutes before 6pm to give people chance to enter.\
Once the clock hits 6PM the door will be locked and the event will start.\
Every player in the room must fight until there is 1 Last person standing.\
When the clock hits 7PM, the winner can claim a prize from the middle of the room.\
I hope you enjoy my event purely through my own curiosity.
